Povidone-iodine (PVPI) is a water-soluble complex of iodine with polyvinylpyrrolidone (PVP), with from 9.0% to 12.0% available iodine, calculated on a dry basis[1].

PVPI can be further formulated into topical antiseptic products as a solution (with surfactants and/or alcohol), aerosol or ointment at concentrations from 7.5% to 10%. These products are sold over-the-counter (OTC) and used in hospitals for cleansing and disinfecting the skin, preparing the skin preoperatively and treating infections susceptible to iodine.

It works through disruption of pathogen cell walls.

Best of luck.
